BALL-BEARING'.

Application filed December 17, 1910. Serial No. 597,237.84.

Bearings, of which the following is a specification, reference being hadtherein to the accompanying drawing.

My invention relates to ball bearings, and more particularlyto thatclass thereof provided with continuous or uninterrupted' tracks or ways,which offer no impediment or obstruction tothe travel of the ballstherein, and whereby the several parts are held in assembled' relations,thusconsti/tu/ting a bearing of the unit-handling type.

The present improvement contemplates the formation thereof with certainadditional features which facilitate assemblageand also possess otheradvantages as will hereafter appear.

Bearings of the unit-handling type and provided withl uninterruptedYtracks areassembled in various ways, among which may be mentioned theemploymgnigf eccentric displacement according to the well-known Conradinvention. The last-mentioned procedure, namely eccentric displacement,vis ordinarily followed for the introduction of substantially less thanthe full .complement of balls, after which, if additional ones. aredesired, they may be inserted by other means, such as non-full-depthfilling openings, and the'like.y My present invention, however,contemplates the complete assemblage at one time, and this even in thecase of full type bearings, wherein the raceway is entirely or almostfilled with balls.-

To this end I provide on at least one of the rings at the side of thetrack or way, an outwardly inclined.V onvtapered. surface, whichfacilitates the Y assembled position yover the balls when located in thetrack or way of the other ring. Specifically, this inclined surfaceextends throughout-the periphery of the ring, so that it may be placedin its final position by forcing or pressure overan entire complementof-balls located in the other ring. Moreover in the'specic formillustrated, the inclined surface is so located' as to constitute atrack or way for one of the series of balls. In this way, the `inclinedsurface subserves a double function, in'that it not Specification ofLetters Patent.

only facilitates the assemblage of the bearing, but also serversy as atrack or way when the parts are in assembled relation.A

In the accompanying drawings I have shown several modifications of thegeneral idea by way ofeXample, and obviously7 many changes andvariations may be made therein without departing from the spirit of theinvention; and generally speaking, I do not desire to limit myself toany specific form or embodiment, eX-ce )t in so far as such limitationsare specified in the claims.

Referring to the drawings: Figure l, is a side view of a bearingembodying my invention; and F ig. 2 is a transverse section thereof. Thebearing consists of an outer ring A5 and an inner ring B5, the latterbeing formed with two continuous and uninterrupted grooved tracks orways b5 and Z55, adapted to receive the two series of balls and C5. Theouter ring A5 is formed with a grooved track or way a5 adapted t0.engage the series of balls C5, and at one side thereof is provided withan inclined surface E5, intersecting the track or way a5 on a-line abovethe central or lowest line thereof, thus constituting a rib D5, at oneside of the balls C5, whereby the parts are held in proper operativerelations after they are assembled. The inclined or tapered surface E5extends entirely around the ring A5 or-throughout its periphery:

The method of assemblage is as follows: The balls C55 and C5 are firstplaced in their respective tracks or ways of the ring B5. The ming A5 isthen brought into relation with the balls by placing the inclined ortapered surface E5 in Contact with the series of balls C5. The ring isthen pressed orv forced into its final position, which opera- OIlllfacilitatedby/ the surface E5, as" it "prmit'sts'easy movement overthe balls C5,

the central line of the grooved track or way, than is possible inconnection with the bottom. of a non-full-depth lling opening, throughwhich the balls are forced or pressed oneat a time. Not only does thisresult in reducing the liabilityT of the balls to escape, but inaddition greater. resistance to side pressure is thereby'aorded. lt willbe further noted that the inclined surface E5 serves Aalso as a` trackor way in connection with the series of balls CGQ n other lwords whenthe parts are assembled, the rnceway for the balls C" is constituted bythe Agrooved track or way b in the ring B5, and by the inclined ortapered surface E5 of the ring A, it being noted that this raceway isangularly located -so that the balls C may take both radial and endload, in the same manner for instance as the correspondin1r series Aofballs shown in my pre- -vious Letters Patent No. 1,059,538. An-

other advantage arisingfrom this particular form is involved in the factthat, due to the mode of assemblage described, am enabled to dispensewith thel lling opening -as shown in such Letters Patent.

The above described embodiments of my invention are presented heremerely by way of example, and as before stated Amany equivalent formsand variationsl will suggest themselves to those skilled in the artandstill be embodied within the spiritV of my invention.

Having thus described my invention, its

construction and mode of operation, what claim and desire to secure byLetters Patent I of the'United States is as follows:

1. In a ball bearing, the combination of the inner and outer rings and aplurality of series of bal-ls mounted therebetween, one of said ringsbeing formed with a continib ous and uninterrupted track `or way toenuninterrupted tracks or ways, and the other ring` being formed withone continuous or uninterrupted track or Way and further provided at oneside .ofthe track-or way with an outwardly inclined or tapered surfaceof such form as lto allow 'the forcing of the ring over the. rst 'seriesof'balls when located in the other ring, and also toserve as a trackorway 'for the second series of balls.

in testimonyy whereof I have afixed by signature in presence'of twowitnesses.
